An efficient removal of phenol from water by peroxi-electrocoagulation processes

The present study explores the removal of phenol from water by peroxi-electrocoagulation method using mild steel as anode and graphite as cathode. The various parameters like effect of pH, concentration of phenol, current density, temperature, and co-existing ions on the removal efficiency of phenol from the water was studied. These studies were carried out at an initial concentration of phenol of 2.5 mg/L. The results showed that the maximum removal efficiency of 92% was achieved at a current density of 0.10 A/dm(2) and pH of 2.0. The results of pilot scale study show that the process was technologically feasible. (C) 2014 Elsevier Ltd. All rights reserved.
